In 2014, rising mixed-martial-arts stars Conor McGregor and Dustin Poirier met in Las Vegas, both hoping to pave their way to a world championship. Since then, McGregor has won titles in two weight classes, while Poirier secured an interim lightweight crown, both becoming UFC superstars in the process. And on January 23, the two kick off 2021 with what promises to be an epic rematch in UFC 257: Poirier vs. McGregor 2, a free event being televised in Davenport's Rhythm City Casino Resort Rhythm Room.
